This is Freakonomics Radio on Marketplace.

Here's the host of Marketplace, Kyra's Doll.

Time now for a little bit of Freakonomics Radio that moment in the broadcast every couple

of weeks where we talk to Steven Nubner, the co-author of the books and the blog of the

same name, the hidden side of everything is what it's all about.

Dabner, how are you, man?

Doing well, Ky.

Thanks.

Here in New York, we are recovering still from Sandy.

Yes.

The transit system has mostly recovered or subways and buses getting back to moving about seven million

passengers a day, if you can believe it.

Which is, I mean, honestly, it's amazing.

And the fact that they pumped out all that water is kind of crazy.

It is.

And you know, we've been doing it for years and years.

All that mass transit means that New Yorkers have one of the smallest per capita carbon

footprints in the entire United States because we all know that mass transit is very, very

good for the environment, correct?

We do know that.

And the only thing we don't know is where you're going, Dabner.
